    Emotion Regulation, Parasympathetic Function, and Psychological Well-Being
    (Frontiers Media S.A., 2022) Brown, Ryan L.; Chen, Michelle A.; Paoletti, Jensine; Dicker, Eva E.; Wu-Chung, E. Lydia; LeRoy, Angie S.; Majd, Marzieh; Suchting, Robert; Thayer, Julian F.; Fagundes, Christopher P.
    The negative emotions generated following stressful life events can increase one’s risk of depressive symptoms and promote higher levels of perceived stress. The process model of emotion regulation can help distinguish between adaptive and maladaptive emotion regulation strategies to determine who may be at the greatest risk of worse psychological health across the lifespan. Heart rate variability (HRV) may affect these relationships as it indexes aspects of self-regulation, including emotion and behavioral regulation, that enable an individual to dynamically adapt to the changing demands of both internal and external environments. In this study, we expected individual differences in resting vagally mediated HRV to moderate the influence of emotion regulatory strategies among our sample of 267 adults. We found support for the hypothesis that higher vagally mediated HRV buffers against the typical adverse effects of expressive suppression when evaluating depressive symptoms and found weak support when considering perceived stress. There was no evidence for an interaction between cognitive reappraisal and vagally mediated HRV but there was a significant, negative association between cognitive reappraisal and depressive symptoms and perceived stress. Future work may determine if intervening on either emotion regulation strategies or HRV may change these within-persons over time.

    Sociosexual domains as mediators of the relationship between trait depression and sexual risk: A serial mediation analysis in a sample of Iranian American adults
    (Elsevier, 2022) Torbati, Autena; Ullrich, Helen S.; Cano, Miguel À.; Essa, Saman; Harvey, Laura; Arbona, Consuelo; Vaughan, Ellen L.; Majd, Marzieh; Fagundes, Chris; de Dios, Marcel A.
    Background The current study examined sociosexual attitudes and desires as mediators of the relationship between trait depression and sexual risk behaviors (SRB). Method Iranian Americans (n = 152) were recruited and path analyses tested a serial mediation model including the direct and indirect effects of trait depression levels on SRB. Results Trait depression had a significant, indirect effect on SRB through sociosexual attitudes and desires scores, with an indirect effect estimate -.02, SE = 0.01, 95% CI [-0.05, -0.04]. Limitations Study limitations included the use of self-report measures and the lack of longitudinal data. Conclusions Increased levels of trait depression were associated with more unrestricted sociosexual attitudes and desires which, in turn, led to greater levels of sexual risk behaviors. The study findings can serve to inform sexual health interventions for Iranian American adults.
